Stanford -- The Stanford women dominated their first game atop the polls since 2005 with a 77-41 romp over Long Beach State on Sunday at Maples Pavilion.

Forward Joslyn Tinkle led all scorers with 18 points, and two-time reigning Pac-12 Player of the Week Chiney Ogwumike added a double-double, but the story was Stanford point guard Amber Orrange, who ignited the Cardinal offense with 13 points, seven rebounds and nine assists.

Orrange scored Stanford's first seven points and successfully navigated the 49ers' full-court press and half-court trap to dish eight first-half assists. She also hit one of her team's seven first-half threes, out of 10 total.

"Our strategy going into the game was to take away the three-point line, pack it in on Chiney and let Amber shoot the ball," Long Beach State coach Jody Wynn said. "She started out 3-for-3. What are you gonna do?"

Orrange wasn't the only hot first-half shooter for Stanford (6-0), which shot 54.3 percent from the field en route to a 49-point output - its highest in a first half this season.

All told, the Cardinal shot 50 percent from the field and had nine players play double-digit minutes and score. Taylor Greenfield joined in the quartet of double-digit Stanford scorers, chipping in 11, including three three-pointers.

"I thought Amber did a really good job running our team," Stanford head coach Tara VanDerveer said. "... We had a lot of different people contribute, so I like that, too."

Stanford also showcased a stifling defense, holding Long Beach State (3-3) to 27 percent shooting, including 2-for-20 from behind the arc. Guard Alex Sanchez had half of her team's 20 first-half points and finished with 14 to lead the 49ers, who dropped to 1-1 against Pac-12 teams after a Nov. 18 win over Washington.

"They're very skilled," Wynn said of the Cardinal, who extended their home win streak to 81 games. "They're big, they're long, they can shoot the ball."

"They're well-deserving of being the No. 1 team in the nation."

Stanford will take its lofty ranking on the road for seven of its next nine games, including a Dec. 22 game at No. 20 Tennessee and its first three Pac-12 games.

"Our target is growing bigger and bigger, and we want to keep it there," Tinkle said. "We have a lot to keep improving on."
